The Know Nothing movement was an American political movement that operated on a national basis during the mid-1850s.
This flag has an eagle below a ribbon banner bearing Native American and a ballot box bearing the slogan Twenty-One Years, referencing a belief that
United States citizenship should be granted only after an emigrant had lived in this country for 21 years.
Text on second through fourth white stripes reads "Native. Americans./Beware Of/Foreign Influence."
All the Ns are reversed, except the first N in Native.
Another flag had an image of George Washington.
